A power company divides the geographic regions it serves into grids. The company is
able to allocate the power it generates based
on the usage and needs of a particular grid.
Certain grids use more power at certain times
of the day, so companies often shift power
around to different grids at various times. On
any given day, the company makes several
changes in the power allocation to Grid 1.
First, it increases the power by 20%. Then, it
decreases it by 10%. Finally, it increases it by
30%. What is the net percent increase in this
grid's power allocation? Round to the nearest
whole percent and ignore the percent sign
when entering your answer.
